Will Smith, the hardest-working man in showbiz, is apparently going to be working harder in New York. The Los Angeles-based TV/music/movie star is now shopping Manhattan for a four-bedroom rental with a Central Park view.

“He’s looking to spend between $50,000 and $70,000 per month for an unfurnished condo,” says one of our spies.

Smith and his lovely wife, Jada Pinkett Smith, recently purchased a $3.6 million “temporary” home in the San Fernando Valley while construction continues on their 100-acre compound in the Malibu mountains.

The Smiths bought the Malibu ranch, which will have approximately 27,000 square feet of indoor space and equestrian facilities for about $7.5 million in 1999.

But the six-bedroom temporary digs on five acres ain’t so bad, with a wine cellar, media room, a pizza oven, outdoor kitchen, barn, pool and guest house.

Facing forward

The family of Kevyn Aucoin, the late, great makeup artist who made many of the world’s most beautiful women even more beautiful, has put his elegant Chelsea townhouse apartment on the market.

Aucoin, who died in May 2002 from a brain tumor, would command an average of $8,000 a day from his celebrity clients who included Julia Roberts, Gwyneth Paltrow, Janet Jackson, Cher and Sharon Stone. “Kevyn would do my makeup, and I know this sounds corny, but honestly, I felt like I’d been kissed by the beauty gods,” Janet Jackson has said.

Now his cosmetically pleasing Chelsea duplex is being listed for $1.19 million with Douglas Elliman’s Arlene Groder and Linda Gottlieb.

Included in the two-bedroom, 1,250-square-foot residence is a south-facing large garden with exotic plantings, a pond and stone patio.

The double-height living/dining room has beamed ceilings and features a cozy woodburning fireplace.

The sale comes as reports of his company, Kevyn Aucoin Cosmetics, now being run by his father, Izzy Aucoin, 73, a retired lineman for Bell South, and Kevyn’s three siblings from Lafayette, La., is having financial troubles.

The Aucoin family has already sold Kevyn’s 82-acre estate in Middletown, N.Y., for $1.1 million.

The ball-banging babe, who’s famed for her backside, rather than her backhand, has disposed of the Miami Beach penthouse condo at Portofino Tower that she briefly shared with hockey star Sergei Fedorov, for $1.63 million.

According to local news reports, Fedorov, who quietly married the comely blonde in Russia in 2001, and is now her ex, was the buyer of the 5,600-square-foot, three-bedroom apartment with its own pool.

But Kournikova became the seller after the two divorced – and someone got a “killer” deal.

The other two like-sized penthouses in the sky-high tower at the southernmost tip of South Beach have sold for over $5 million.

Meanwhile, the 22-year-old Anna has been playing mixed singles with Latin hearthrob Enrique Iglesias, ever since she made a guest appearance in one of his music videos.

Hirschfeld hijinks

RESIDENTS of old-moneyed 825 Fifth Avenue were chomping at the bit earlier this year with the word that self-promoting parking-lot mogul-cum-parolee Abe Hirschfeld was about to sell his two apartments there.

“They want him out in the worst way,” says one resident of the building, which is home to various members of the du Pont and Auchincloss families.

Unfortunately, Hirschfeld’s most recent deal (the two places were on the market for $6.9 million), fell through.

Hirschfeld’s latest broker, Rica Tarnoff of Alice F. Mason, could not be reached.

Queen of Red Hook

Remember those glamorous ads with Queen of Mean Leona Helmsley in one of her luxury Manhattan hotels?

We’ll probably never see her doing a similar campaign in Red Hook, yet the Helmsley-Spear company is now planning a residential project at Imlay Street.

According to Post Brooklyn bureau chief Gersh Kuntzman, the site is currently zoned for manufacturing. While approval for residences is expected to be rubber-stamped soon, Helmsley-Spear – showing some of the chutzpah from when Leona reigned supreme – is already advertising the buildings as a done residential deal.
